The DAME project Professor Jim Austin University of York

Origins • Funded by EPSRC under the governments e. Science initiative. • Total government funds in e. Science exceeds £ 220 M • Started as a result of existing work at the collaborators sites • Built on the WRG metropolitan Grid • Few of us were Grid experts at the start! Distributed Aircraft Maintenance Environment - DAME

Project Partners • EPSRC Funded, £ 3. 2 Million, 3 years, commenced Jan 2002. • UK pilot project for e-Science • Aims to show the utility of Grid computing for data and compute intensive engineering problems • A generic system applicable in many domains Distributed Aircraft Maintenance Environment - DAME

Partners • 4 Universities: – University of York, Dept of Computer Science (lead) – University of Sheffield, Dept of Automatic Control and Systems Engineering – University of Oxford, Dept of Engineering Science – University of Leeds, School of Computing and School of Mechanical Engineering • Industrial Partners: – Rolls-Royce – Data Systems and Solutions – Cybula Ltd Distributed Aircraft Maintenance Environment - DAME

DAME Grid Challenges • Building a demonstration system as proof of concept for Grid technology in the aerospace diagnostic domain. • Two primary Grid challenges: – Management of large, distributed and heterogeneous data repositories; – Rapid data mining and analysis of fault data; • Other key (commercial) issues: – Remote, secure access to flight data and other operational data and resources; – Management of distributed users and resources; – Quality of Service issues (and Service Level Agreements) Distributed Aircraft Maintenance Environment - DAME

The Data • Each flight could produce up to 1 GB of vibration data • This is archived in distributed data repositories (EDS) Distributed Aircraft Maintenance Environment - DAME

Demonstrator Objectives The DAME demonstration system provides a diagnosis workbench (portal) which brings together a suite of analysis services via Grid technology; – Provides access to a range of analysis tools for the engine diagnosis process – Will act as central control point for automated workflows – Manages issues of distributed diagnosis team and virtual organisations – Manages issues of security and user roles.
